1 Quart 100% Pure Fumed Silica Powder, Advanced Thickener for Epoxy, Paints, Varnishes, Professional Fumed Silica for Filling Cracks and Voids, Worked Well for Ceramic Blanket Rigidizer - by TITGGI

Works great

If you are looking for fumed silicate for the dry water science experiment this is not the correct kind and will not work. So glad we did a practice run before the birthday party.

I do resin art, sometimes I get it too runny so I put a little this magic stuff and poof I can it helps me correct a lot of mistakes I would recommend it to anyone who deals with any type of product were consistency is important and sometimes when it gets too runny this helps and if I understand correctly it is food grade, but it did an outstanding job for me big thumbs up

The seal cover was opened on this product, yellowish and weird odor!!!

I use this to thicken my last epoxy cast pour. I cast trout head with epoxy smooth on and I use this for last pour to thicken and strengthen it and it works great.

This product worked exactly as I had hoped it would. My only caution is that you open it in a room with still air, because it is extremely light--think of it as a container full of feathers: You wouldnt think of opening a container of feathers outdoors, so think you this product in the same way. As for how to use it: Mix your resin and hardener completely before adding the fumed silica. Then mix it thoroughly to eliminate any lumps before applying it to whatever surface or volume you intend to. It worked for me and it will work for you. I recommend it.

Works as it should when mixed with polyaspartic for filling concrete cracks.

This is the right silica to get to mix up your own rigidizer.

Was exactly what I expected. Haven’t used it yet, but have no reason to think it won’t work.

Using fumed silica and chop fiberglass stran helps quiet abit to thicken epoxy.
